Manifold Installation
Procedure
The Rosemount 305 is available in two designs: Traditional and Coplanar.
The traditional 305 Integral Manifold can be mounted to most primary
elements with mounting adapters in the market today. The Rosemount 306
In-Line Manifold is used with In-line transmitters to provide block-and-bleed
valve capabilities of up to 10000 psi (690 bar). The Rosemount 304 comes in
two basic styles: traditional (flange x flange and flange x pipe) and wafer. The
304 traditional manifold comes in 2, 3, and 5-valve configurations. The 304
wafer manifold comes in 3 and 5 valve configurations.
CONVENTIONAL
To install a 305 Integral Manifold to a 3051S transmitter:
1. Inspect the Teflon SuperModule O-rings. If the O-rings are undamaged,
reusing them is recommended. If the O-rings are damaged (if they have
nicks or cuts, for example), replace them with new O-rings.
IMPORTANT
If replacing the O-rings, be careful not to scratch or deface the O-ring grooves
or the surface of the isolating diaphragm when removing the damaged
O-rings.
2. Install the Integral Manifold on the SuperModule. Use the four manifold
bolts for alignment. Finger tighten the bolts, then tighten the bolts
incrementally in a cross pattern to final torque value. See "Flange Bolts"
on page 2-6 for complete bolt installation information and torque values.
When fully tightened, the bolts should extend through the top of the
module housing.
3. If the Teflon SuperModule O-rings have been replaced, the flange bolts
should be re-tightened after installation to compensate for cold flow of
the O-rings.
4. If applicable, install flange adapters on the process end of the manifold
using the 1.75-in. flange bolts supplied with the transmitter.
